  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Reference will now be made in detail to the preferred embodiment of the present invention.
  • Referring to FIGS. 1-6, an electrical card connector 100 of the present invention, comprises an insulative housing 1, a plurality of contacts 2 retained in the insulative housing 1, an ejector 3 assembled at a left side and a rear side of the insulative housing 1, a switch element 4 formed at the rear side of the insulative housing 1, and a metal shell 5 covering the insulative housing 1 for defining a receiving space 10. The electrical card connector 100 is capable of alternatively receiving two cards, namely a SIM card 7 and a micro SD card 8. The electrical card connector 100 further comprises a tray member 6. The tray member 6 is received in the receiving space 10 for receiving the SIM card 7 when the SIM card 7 is in use. The tray member 6 is drawn from the receiving space 10 when the micro SD card 8 is inserted in the receiving space 10 for use. The terms of “left, rear” are not meant to be limiting but is descriptive of depiction according to the claims.
  • Referring to FIGS. 3 and 4, the insulative housing 1 comprises a base portion 11, a pair of left/right sidewalls 12 extending upwardly from two lateral edges of the base portion 11, and a rear wall 13 extending upwardly from the rear edge of the base portion 11. The metal shell 5 cooperates with the base portion 11, the left/right sidewalls 12, and the rear wall 13 for defining the receiving space 10. The left sidewall 12 defines a lengthwise slit 121 for assembling a shaft 31 of the ejector 3. The rear wall 13 defines a transverse slot 131 adjacent to the right sidewall 12 for positioning the switch element 4. The base portion 11 forms a pole 111 extending upwardly to beside the rear wall 13 for pivotally positioning an actuator 32 of the ejector 3. The right sidewall 12 defines a cutout 122 communicating with the receiving space 10 and exterior. The cutout 122 has a slant surface 1221 facing towards the receiving space 10.
  • Referring to FIGS. 3 and 4, the contacts 2 comprises a number of first contacts 211, a number of second contacts 212, and a number of third contacts 221 respectively positioned in three different rows. The first contacts 211 are positioned at front of the second contacts 212 and the third contacts 221 along a front-and-rear direction and space away from the second contacts 212 and the third contacts 221 for a certain distance in the front-and-rear direction. A number of the first contacts 211 is three, a number of the second contacts 212 is three, and a number of the third contacts 221 is five in the present embodiment of the invention. The number of the second contacts 212 is smaller than that of the third contacts 221. Therefore, the second contacts 212 are scattered into the third contacts 221. Three of the second contacts 212 and four of five third contacts 221 adjacent thereto are staggered with each other in a transverse direction perpendicular to the front-and-rear direction. Each of the contacts 2 has a soldering portion 23 and a contacting portion 24 extending backwardly and upwardly from the soldering portion 23. The first soldering portions 2113 of the first contacts 211 are positioned in a first, forefront straight line which is adjacent to an insertion opening through which the tray member 6 is inserted into the receiving space 10. The first contacting portions 2114 of the first contacts 211 are positioned in a second straight line farther to the insertion opening than the first soldering portion 2113. The second soldering portions 2123 of the second contacts 212 and the third soldering portions 2213 of the third contacts 221 are positioned in a third, same straight line farther to the insertion opening than the first contacting portions 2114 of the first contacts 211. The second contacting portions 2124 of the second contacts 212 are positioned in a fourth straight line farther to the insertion opening than the second, third soldering portions 2123, 2213 of the second, third contacts 212, 221. The third contacting portions 2214 of the third contacts 221 are positioned in a fifth straight line farthest to the insertion opening in all the soldering portions 23 and all the contacting portions 24 of the contacts 2.
  • Referring to FIGS. 3 and 4, generally speaking, the first contacting portions 2114, the second contacting portions 2124, and the third contacting portions 2214 are positioned in three different straight lines, the second soldering portions 2123 and the third soldering portions 2213 are positioned in the same straight line, and the first soldering portions 2113 is positioned in another straight line different from the second, third soldering portions 2113, 2123. Because the especial layout of the contacts 2, the first contacts 211 and the second contacts 212 are cooperatively combined into a first terminal group 21 for engaging with a SIM card 7, while the second contacts 212 and the third contacts 221 are cooperatively combined into a second terminal group 22 for engaging with a micro SD card 8. Therefore, the second contacts 212 are shared by the first terminal group 21 and the second terminal group 22. Two adjacent first contacts 211 have an interspace substantially twice as large as that of two adjacent second and third contacts 212, 221 of the second terminal group 22.
  • Referring to FIG. 3, the tray member 6 comprises a main portion 61 and a door portion 62 formed at a front side of the main portion 61. The main portion 61 has an outline substantially same as that of the micro SD card 8 and has a recess 611 substantially same as that of the SIM card 7. The main portion 61 has a protrusion 612 protruding outwardly and therefore, a notch 613 is defined at front of the protrusion 612 and a guiding surface 614 is defined behind the protrusion 612, just similar to the micro SD card 8 having a protrusion 81 with a notch 82 at front of the protrusion 81 and a guiding surface 83 behind the protrusion 81. When the tray member 6 is inserted in the receiving space 10, the SIM card 7 is received in the recess 611 of tray member 6 for engaging with the first terminal group 21. The metal shell 5 has a flexible beam 54 elastically extending into the notch 613 of the tray member 6 for securing the tray member 6 in the receiving space 10 at a final position. The protrusion 612 is received in the cutout 122. When the tray member 6 is drawn from the receiving space 10, the micro SD card 8 is received in the receiving space 10 for engaging with the second terminal group 22. The flexible beam 54 of the metal shell 5 elastically extend into the notch 82 of the micro SD card 8 for securing the micro SD card 8 in the receiving space 10 at a final position.
  • Therefore, the second contacts 212 are shared by the first terminal group 21 and the second terminal group 22, the electrical connector 100 of the present invention saves occupied spaces of the contacts 2.
  • While a preferred embodiment in accordance with the present invention has been shown and described, equivalent modifications and changes known to persons skilled in the art according to the spirit of the present invention are considered within the scope of the present invention as described in the appended claims.
